Had to go to Ada today for work. I took DSD along with a real crappy telescoping antenna.

Below is the output of the DSDPlus.P25data file for the few sites I was able to receive.

You've confirmed Seminole (26.26). I've added it to the DB and have updated peer/neighors on Weleetka and Preston. Thanks!

wx5uif · Nov 17, 2020

Also receiving this tonight from my home. Possibly Spavinaw?

Excellent -- That's the Spavinaw OK (Mayes) site - FCC Callsign WPSE994 (American Electric Power Service Corporation)

And 1F9-15.15 is probably VInita OK (Craig) site - FCC Callsign WPFP340 (American Electric Power Service Corporation)

I'll get 1F9-14.14 added to the DB. Thanks!

wx5uif · Nov 18, 2020

I'll try to get around to the Vinita area soon to confirm.

I had to go to Pawhuska today for work. No P25 CC to be found. I did find what sounded like EDACS CC on the air still.

b1tr41d · Nov 19, 2020

It would appear that Bartlesville just flipped over to P25 yesterday afternoon.
1F9 is the system ID and its showing as site 18.
Showing CC of 855.9125 and four talk channels.
I'll grab more info and submit it to the DB later today.

mtindor · Nov 19, 2020

Oklahomans (and DXers),

With the exception of some upcoming information from @b1tr41d that should confirm Bartlesville, below is the list of sites observed online (based upon neighbor/peer lists) and their likely location. These sites need to be confirmed.

When I say confirmed, we need primary/alt CCs, NAC, full peer/neighbor list including the frequencies of the peers/neighbors. And we need to be able to confirm (either by all of the active freqs being on an FCC license or a person sitting in front of a tower with their antenna off) the locations. Typically we can confirm the location based upon (a) active frequencies and looking those freqs up in the FCC database and (b) peer/neighbor lists.
The columns below that lists frequencies are the frequencies known to have been active CCs at one time or another for a given site
Peers/neighbors on all sites are likely to change over time as more and more sites come online and until the system is fully built out
There is some indication that at least some of the sites are switching SysID-Site ID from 1F9-##.## to 1FA-##.##. Not sure what to make of that
Be on the lookout for anything with WACN 92715, and SysID 1F9 or 1FA.
Since the CC can change for a given site at any given time, you'll need to look at all frequencies on a site to find a P25 CC. [The current CC may not be one of the ones listed below] I have listed the callsigns for these sites, with direct links to FCC database (to make sure you are viewing most up-to-date info).

I was curious if that was a decoding error, or if that has been confirmed by multiple sources.

I think it has only been revealed by one source thus far. But, in the past (in Ohio) they certainly changed SysIDs halfway in. So it very well could be a valid thing happening and not a decoding error. Then again, it could be a decoding error.

wx5uif · Nov 19, 2020

No decoding error. I get Leonard so well that I have to drop the gain down considerably on my SDRs. The SDS200 also shows the 1FA network as well. This has been checked several times over.

wx5uif · Nov 19, 2020

Soooooooooo.... Earlier (4 or so hours) Leonard was showing the 1FA network. Now it is showing again on the 1F9 network.

It is showing different CC / SCC then was was displaying earlier on the 1FA system. (The 1FA was CC:854.7625 / SCC:855.7875) Both those do not show an active CC now.

I think it just likes to keep mtindor busy!

LOL. I wonder if they had a failure of some equipment, brought in a piece of equipment from elsewhere and reprogrammed it -- and while it was initially online it was showing old info. That might have been what happenned.

I've updated Leonard in the DB back to 1F9-10.10. And I see useful information in the peer list.

1F9-7.7 856.3375 might be Pawhuska OK (Osage) - WPCM984

mtindor · Nov 19, 2020

For Oklahomans (and DXers of Oklahoma sites), if you can copy any already-known sites that are in the DB or any new ones, please gather updated screenshots and post them. Control channels change frequently ; peer/neighbor lists are always changing as the system is being built out. For DSDPlus users, a fresh screenshot of sites you can copy (from 11-19-2020 or newer) would be nice.

@b1tr41d Just a friendly reminder to submit that info when you get a chance.

Thanks!

b1tr41d · Nov 20, 2020

Yes. Thank you for your patience. Just submitted what I've confirmed.
Unitrunker reported some weird entries with the voice channels.
Same frequencies different LCN's. (See attached screenshot)
Not sure if they are messing with the channels still or if Unitrunker isn't reporting correctly.

That's normal because it's a phase II system.
Look at the LCNs and band plans. Band plan 00 is for phase I and should only be on the control channels and alternate control channels.
If there are any phase I talkgroups they will also use 00 LCNs.
Band plan 08 is for the phase II voice channels. Each voice channel will have two consecutive LCNs that start with 08 for time slots 1 and 2.

Duh!
That makes sense.
Forgot this was a PII system.
I'll make another submission here shortly with the updated info.

Looks like somebody at AEP fat-fingered the freqs when they set them. IT is supposed to be 855.4375, not 854.5375. Hopefully they will fix it. I'm going to add 854.5375 though, since that's what it's currently broadcasting on the control channel.

Thank you. You don't happen to have the frequencies associated with the peers (11.11, 46.46, 48.48) that you provided in the submission, do you? I know that DSDPlus and Proscan will show the frequencies that are the current CCs of the peers/neighbors, but I don't know if Unitrunker shows the actual frequencies or just shows 0.0. If you were to look at the 1F9 system in Unitrunker, and then click on teh Channels tab, you could then scroll down until you found any frequencies showing for 1F9-11.11, and 1F9-46.46 (we already know 48). Can you check and see if the frequencies are available?

I have added this new site to the DB. Thanks again!
